Exercise – An exercise for demonstrating the ubiquitous nature of operations is to ask the class to identify every service they have encountered from waking up in the morning through to going to bed at night, for example, the radio alarm that wakes them up depends on the operations of the radio station; the water in which they wash was delivered (presumably) by a water utility;

the public transport operation that transported them to college, etc. through to the bar, or other place of entertainment that they finish the day with.
